As found via Scoble Microsoft just released videos of Microsoft's recent developer conference (PDC05). These will be online only for six months :
http://microsoft.sitestream.com/PDC05/
(Update: This link requires Internet Explorer)
The session search on the page sucks - very confusing and basically unusable unless you have a list of the sessions handy.
Here is the trick - search sessions here

I'm still pissed that I have never received the PDC03 DVD set I paid $199 for - none of my emails were responded (in two years) and they couldn't tell me anything while on PDC05 - there was obviously a different team this year :( Not that I need that DVD set two years later :)
But, anyway, it's great to see MS provide this year videos for free!
